This study explored three aspects
of classroom discourse that was conducted in elementary science classroom by a
Vygotskian manner. Disciplinary content of conversations was matter (atomic
structure) and modelling. Through a validated analytical framework,
communicative approaches, teaching purposes and patterns of interactions were
analysed. It was found that the teacher enacted both authoritative and dialogic
sides of teaching episodes. Regarding teaching purposes, the teacher guided the
students for engaging in a travel between micro (part), macro (whole) and
symbolic (communicative) dimensions by negotiating atoms and modelling.
Regarding teaching purposes, the teacher directed the students to interrogate
challenges to compose models that were expected to incorporate reality. Regarding
patterns of interactions, teacher-student exchanges were pervasive among others
(e.g., student-student). These findings were discussed by taking current
theories of classroom discourse into account and recommendations were offered
for teachers’ professional development.
